.To all whom it may concern:

Be it known that we, JAHN K. MARTINKA, and ELIZI K. MARTINKA, citizens of Czecho- Slovakia, residin at New York, in the county of New 'ork and State of New York, have invented certain new and useful llmprovernentsin Egg-Testers, of which the following is a specification.

lhis invention relates to certain new and useful improvements in egg testers of that typeembodying a receptacle having an open top interiorly shaped to snugly engage a portion of an egg so as to provide a seat for the latter` and a mirror in the receptacle beneath the open top for redecting such light as passes through the egg, the light being observable through a side opening provided in the side of the receptacle at a convenient point above the mirror.

'llheA primary object of the invention is to provide an egg tester-of this kind which is extremely simple and durable in construction as well as capable of being placed into eilicient and practical use by a relatively unskilled person, which is made more readily possible by the provision of means for adjusting the mirror toward or away from the egg and side opening so as to obtain proper reflection.

:With the above and other objects in view, the present invention consists in the novel form, combination and arrangement of parts hereinafter more fully described 'and shown in the accompanying drawings,

in which like reference characters designate vcorresponding parts throughout the several views.

lin the drawing, Figure 1 is a view partly in elevation and partly in vertical section of an egg tester constructed in accordance with the present invention,

Fig. 2 is a horizontal sectional view thereof taken substantially upon line II--II of Fig. 1 and Fig. 3 is an elevational view of the same with parts broken away.

Referring more in detail to the several` views, the present invention embodies a receptacle including an upright tubular body 5 having open ends and with the interior of its upper end shaped as at. 6 to conform to a portion of an egg 7 so as t9 provide a seat for the latter whereb it isv supported in position as shown in igs. 1

and 2, partially, within the open upper end of said body. The body 5 is provided with a removable bottom 8 which may` be detachably held in place or secured to the body 5 by any suitable means such as the pin and bayonet slot connections 9 upon opposite sides thereof. Suitable resilient supporting legs 10 are rigidly fastened in any ysuitable manner to the bottom member 8 whereby the receptacle is supported in spaced relation to a table or the like on which the device is placed.

An adjusting screw 11 is positioned centrally of the bottom member 8 and in threaded engagement therewith so as to extend axially within the body 5 and a supporting member 12 slightly smaller in diameter than the internal diameter of the body 5 is supported upon the upper end of the screw 11 and carries a mirror 18 as shown in F ig. 2 arranged directly beneath the egg 7. The lower end of the screw 11, exteriorly of the receptacle, is provided with a wing handle 14 for permitting the screw 11 to be readily turned so as to adjust the mirror 13 to any desired extent longitudinally of the receptacle whereby it is brought closer to or farther away from the egg 7 so as to insure most practical results by properly reflecting the light for being viewed through the side opening 15 provided 'in the body 5, under varying light conditions. Handles 16 are carrled by the opposite sides of the body 5 to facilitate the moving of the/tester.

In operation, the l@Egg is placed upon the seat 6 as shown in igs. 1 and 2 and external light passes through the egg and the open upper end of the body 5 to the reflector 13 where it can be viewed through the opening l5. The relative freshness of the egg can be thus readily ascertained by noting the brightness of the light inl the reflector, it being a well known fact that a 'fresh egg will permit the passage of light there' through more freely than an egg which is not so fresh or which isnot goo o From the foregoing description, it is believed that the construction and operation of the present invention will be readily understood and appreciated by those skilled in the art. y

Minor changes may bemade without departing from the spirit and scope of the invention as claimed.

5 teriorlyto conform-to a What is claimed as new is: An egg tester including an upright rei cepitacle having a tubular body portion provi ed with an open upper end formed inrtion of an egg for providing a supportlng seat therefor and provided with a `sight ope `in the side thereof immediately below t e open upper end, a detachable bottom plate, car- 10 rymg supporting legs, for the sald tubular body, a removable reflector within the body portion and vertically adjustable therein, and a single supporting bar' centrally attached to said reflector and screw-threadedly "nounted within the central portion of the `removable body In testimony whereof we aiiix our signaplate.
